Active Recombinant Cynomolgus IL4 protein, Fc-tagged

• Cat.No.: IL4-0174C
• Product Overview: Recombinant Cynomolgus IL4 protein(His25-Ser153), fused with Fc tag, was expressed in HEK293.

Specification

• Species: Cynomolgus
• Source: HEK293
• Tag: Fc
• Protein Length: 25-153 a.a.
• Form: Lyophilized from 0.22 μm filtered solution in 51 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Cynomolgus / Rhesus macaque IL-4 R alpha, His Tag at 5 μg/mL (100 μL/well) can bind Cynomolgus IL-4, Fc Tag with a linear range of 0.1-4 ng/mL.
• Molecular Mass: This protein carries a human IgG1 Fc tag at the C-terminus.The protein has a calculated MW of 41.4 kDa. The protein migrates as 46-50 kDa and 53 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Proteinlength: His25-Ser153
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >90% as determined by SDS-PAGE.>90% as determined by SEC-MALS.
• Storage: For long term, the product should be stored at lyophilized state at -20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after at:
  -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
